Glad you like the demo! :) Just wanted to make sure; did you download the updated version of the demo? It was uploaded about 14 days ago, and fixed some of the issues you're talking about (Different speakers had different colored text - blue, green, black etc) Let me know, thanks!
Yes, it was the new update. I didn't have a hard time differentiating who was talking (the colors helped in that regard). It's when I'm choosing my own responses. The way it's handled now is fine, but it would be quicker to know which dialogue choice you're picking if there was a small dot or something in front of the choice you're highlighting. Oh, another option is to maybe italicize the option you're highlighting.
